Hi Donghoon,
The ProvenanceRecorder class captures provenance information
from workflow events, but Recording classes are responsible
for writing this to a specific type of output such as a database.
(i.e., there's no database connections in ProvenanceRecorder.)
The default provenance settings use SQLRecordingV8.java. If you
want to perform a query after the workflow finishes execution,
you can add the query to executionStop() in this class.

Dear Kepler folks and Daniel,
I have a question for DB connection when the value of an actor (constant
actor) is changed.
Suppose that a user changes a value of an each after executing a workflow.
I checked the source code with debugging mode.
But I can not find where DB is reconnected (see attached)
Actually, I am trying to extract some data after finishing the recording in
wrapup() in ProvenanceRecorder class.
How do I add SQL query like below in ProvenanceRecorder with DB connection?
=====
ResultSet result = null;
try
{
result = _psWorkflows.executeQuery();
while(result.next())
{
if(result.getString("name").equals(workflow))
{
retval = result.getInt("id");
break;
}
}
}

Please, let me know if you need more information.
Thank you~
